Abstract: The invention provides the possibility of incorporating various fixed punching stations within a single compact frame, being applicable especially to the punching of holes in the flanges of angular profiles. The punching cylinders to which the punches and punch-holders are fastened, as well as the dies and the die-holders fastened to the compact frame, allow the punching of holes at the different radial distances required in the flanges of said angular profiles.

It is possible to select pairs of punches and dies having same eccentricity. The punch-holders and the die-holders are equipped with means for angular positioning in the respective cylinder and the compact frame.

Abstract: A novel method and apparatus for producing an endless flexible seamed belt using a punch and die is disclosed. The punch and die have patterned edges in the form of a puzzle cut pattern with extremely small nodes and kerfs. The cutting tolerances of the patterned edges make it necessary to fix the punch with respect to the die so that there is no misalignment of the punch and die between cutting operations. This is accomplished by resiliently fixing the punch to the die, rather than having the punch attached to the force generating assembly as in normal punch and die assemblies. Belt material is positioned between a stock gap between the punch and die and the force generating assembly is activated to provide the cutting force. Once the belt material is cut, the cutting force is removed and the force generating assembly returns to its retracted position. There are two cutting edges on the punch and die so that a first end of one belt and a second end of another belt are formed in a single cutting operation.

Abstract: A linerless label dispenser includes a cutting mechanism. Linerless labels are transported from a roll underneath a plastic guide and onto an adhesive-release material guide structure/ramp past a sensor to a print head which prints indicia on the release material coated face of the labels. From the print head and cooperating print roller the labels pass to a plasma coated stripper surface which is disposed at an upwardly directed angle between about 20-35.degree. with respect to the horizontal, and into contact with a plasma coated stationary anvil blade. The anvil blade is spaced downwardly from the stripper surface a distance of about 0.001-0.008 inches (preferably about 0.002-0.004 inches) and cooperates with a plasma coated or texture painted rotary blade of a rotary cutter. Downstream of the blades may be a plasma coated exit roller typically cooperating with a hold down mechanism for dispensing individual cut labels.

Abstract: System for controlling slugs (10, 10') in a stamping and forming machine has a slug stripper (32) for stripping slugs from the end (13) of the punch (11) and slug supporting bars (78, 80) which support slugs at their edges as they move through a passageway (82). The slug stripper (32) is mounted in the facial surface (18) of the die plate (14) and has an end portion (56) which extends partially over the die opening (44). When the punch (11) descends and punches a notch (8) in the strip material (2), the slug (10, 10') which is produced moves the stripper (32) to a retracted position. When the slug (10, 10') is moved past the end of the slug stripper (32), the slug stripper returns to its normal position so that on the return stroke of the punch the slug will be removed by the end portion (58) of the stripper. The slugs are maintained in a stack in the slug passageway (82) by opposed supporting bars (78, 80) which are resiliently biased against opposite edges of the slugs.

Abstract: Precut pieces of wood of like configuration are stacked in a hopper from the lower end of which they are advanced one-by-one by a reciprocable pusher onto a horizontally disposed work station. As soon as a workpiece is positioned on the station it is automatically clamped into place, after which two rotary saws, which are mounted adjacent opposite ends of the station, are reciprocated from retracted to advanced positions, during which movement they cut away portions of the workpiece at opposite ends thereof. As soon as the saws have advanced passed the workpiece, they are retracted slightly away from opposite ends of the workpiece, so that they will not reengage the workpiece when they return to their starting positions. When the saws are retracted the now-cut workpiece is automatically released and then ejected from the work station, after which a cycling relay automatically causes another workpiece to be shifted onto the work station so that the above-noted steps are repeated.
